Description

Technical Field

[0001] The utility model belongs to the field of reclining chairs, and in particular relates to a special cushion for reclining chairs which is convenient for fixing and disassembling. Background Art

[0002] A special cushion for a reclining chair is a cushion applied to a reclining chair so that the reclining chair can be used well.

[0003] The patent application with announcement number CN210169513U discloses a special cushion for recliners that is easy to fix and disassemble. Paragraph 0035 of its specification discloses: the limit rod is separated from the limit groove, and the rotating rod is driven to rotate in the opposite direction by the stored force of the torsion spring, thereby facilitating the unwinding of the wound fixing belt, making the length of the fixing belt longer, and facilitating the separation of the fixing belt from the recliner, thereby making it easier to disassemble the main body of the cushion from the recliner.

[0004] However, in actual use, the rotating rod needs to be positioned inside the fixed frame through a limit rod. Since there is no positioning structure at the contact point between one end of the limit rod and the fixed frame, it is easy for one end of the limit rod to fall off from one side of the fixed frame, thereby causing the fixing belt to separate from the recliner.

[0005] Therefore, a special cushion for a reclining chair that is convenient for fixing and disassembling is proposed to solve the above-mentioned drawbacks. Utility Model Content

DETAILED DESCRIPTION

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] See also Figure 1-4 As shown, in this embodiment, a special cushion for a recliner that is easy to fix and disassemble is provided, including a special cushion body 1, a plurality of fixing tubes 106 are provided on one side of the special cushion body 1, and a fixing belt 105 is installed on the outer wall of the fixing tube 106;

[0031] There are multiple circular plates 2 located on one side of the special pad body 1. The internal rotation of the circular plate 2 is matched with the threaded rod 202. One end of the fixing belt 105 is installed on the threaded rod 202. One side of the circular plate 2 is elastically and slidingly matched with a cross-shaped plate 205. One side of the cross-shaped plate 205 is rotatably matched with an annular plate 212. The annular plate 212 is threadedly matched with one end of the threaded rod 202. An annular column 209 is installed at one end of the threaded rod 202. The annular column 209 is snap-fitted with the annular plate 212.

[0032] Working principle:

[0033] First, put the special cushion body 1 on the recliner, and then rotate the threaded rod 202. The threaded rod 202 drives the fixing belt 105 to be stored. One end of the fixing belt 105 fixes the special cushion body 1 on the recliner. Then rotate the annular plate 212. The annular plate 212 moves on one end of the threaded rod 202. The annular plate 212 drives the cross-shaped plate 205 to snap into place on one side of the annular column 209. The annular column 209 positions the threaded rod 202 inside the circular plate 2, thereby completing the fixation of the special cushion body 1.

[0034] The annular plate 212 is set so that the annular plate 212 can be threadedly engaged on one end of the threaded rod 202 under the action of the staff. The annular plate 212 drives the cross-shaped plate 205 to be clamped and engaged on one side of the annular column 209, and drives the threaded rod 202 through the annular column 209 to store the fixing belt 105, thereby reducing the problem of one end of the limit rod falling off from one side of the fixing frame in the prior art, reducing the problem of the special cushion body 1 being separated from the recliner, and making the process of disassembling and assembling the special cushion body 1 more convenient.

[0035] In order to make the threaded rod 202 of this embodiment rotate more stably on one side of the dedicated pad body 1, the following structure is used for improvement: Figure 1-4 As shown, the circular plate 2 of this embodiment is provided with two grooves 213 and two first through holes 201, the threaded rod 202 is rotatably fitted inside the first through holes 201, one end of the threaded rod 202 is provided with a rotating disk 203, one side of the circular plate 2 is provided with two guide posts 204, one end of the guide posts 204 is provided with a sliding disk 207, one side of the cross-shaped plate 205 is provided with two first guide holes 206, the guide posts 204 are located inside the first guide holes 206, and the circular plate 2 is provided with a plurality of grooves 213 and two first through holes 201. Two springs 208 are installed between one side and one side of the cross-shaped plate 205. The springs 208 are sleeved on the circumference of the guide column 204. A second through hole 211 is opened on one side of the cross-shaped plate 205. The annular plate 212 is rotatably fitted inside the second through hole 211. The inner wall of the annular plate 212 is provided with an internal thread, and the internal thread is threadedly fitted with one end of the threaded rod 202. Two pointed heads 210 are installed on one side of the cross-shaped plate 205, and one end of the pointed head 210 is fitted with one side of the annular column 209.

[0036] When using this embodiment, first rotate the rotating disk 203, and the rotating disk 203 drives the threaded rod 202 to rotate inside the first through hole 201, and the threaded rod 202 receives and processes the fixing belt 105, and then rotate the annular plate 212, and the annular plate 212 rotates inside the cross-shaped plate 205 through the second through hole 211. The annular plate 212 is threadedly engaged with one end of the threaded rod 202 through the internal thread, and the annular plate 212 drives the cross-shaped plate 205 to slide on the guide column 204 and compress the spring 208. The cross-shaped plate 205 drives the pointed head 210 to be positioned on one side of the annular column 209, thereby fixing the special pad body 1 on the recliner.

[0037] The first through hole 201 is set so that the threaded rod 202 can rotate inside the first through hole 201 under the action of the rotating disk 203, and the rotation direction of the threaded rod 202 is guided by the first through hole 201, thereby reducing the problem of the threaded rod 202 tilting during rotation and improving the stability of the threaded rod 202 during rotation.

[0038] In order to make the sliding process of the T-shaped block 103 on one side of the special pad body 1 more stable, the following structure is used to improve it. Figure 1-2 As shown, a plurality of T-slots 101 are provided on one side of the special pad body 1 of this embodiment, a guide rod 102 is installed inside the T-slot 101, a fixing cylinder 106 is installed at one end of the fixing belt 105, and the fixing cylinder 106 is sleeved on the circumference of the guide rod 102, and T-blocks 103 are installed at both ends of the fixing cylinder 106, and the T-block 103 is slidably fitted inside the T-slot 101, and a second guide hole 104 is provided on one side of the T-block 103, and the guide rod 102 is located inside the second guide hole 104.

[0039] When this embodiment is in use, when the fixing belt 105 moves, the fixing belt 105 drives the fixing cylinder 106 to slide on the guide rod 102, and the fixing cylinder 106 drives the T-shaped block 103 to slide inside the T-shaped groove 101, and the T-shaped block 103 slides on the guide rod 102 through the second guide hole 104.

[0040] The T-slot 101 is provided so that the T-block 103 can slide inside the T-slot 101 under the action of the fixing cylinder 106, and the sliding direction of the T-block 103 is guided by the T-slot 101, thereby reducing the problem of the T-block 103 sliding out of the T-slot 101 and improving the stability of the T-block 103 when sliding.

[0041] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
